UNION SQL的SQL Server问题

问题描述 投票：1回答：3

我的查询有问题。

消息205，级别16，状态1，行5使用UNION，INTERSECT或EXCEPT运算符组合的所有查询在其目标列表中必须具有相同数量的表达式。

我是基本用户（仍在学习SQL）。

我在这里结合了几个选择我的代码：

我想在FCRR旁边找到类别。

我尝试了很多组合但失败了:(

谢谢您的帮助，

您好B House的评论帮助了我:)

这里的解决方案：

SELECT cast(100 * ([FCRR] / CASESCOUNT) AS DECIMAL(5, 2)) AS [FCRR]
    ,CATEGORY
FROM (
    SELECT cast(count(*) AS DECIMAL(5, 2)) AS [FCRR]
        ,'1 Time' AS [CATEGORY]
        ,DATENAME(MONTH, [TICKET_CLOSED]) AS [MONTH_NAME]
        ,MONTH([TICKET_CLOSED]) AS [MONTH_NUMBER]
        ,YEAR([TICKET_CLOSED]) AS [YEARS]
    FROM [PL_Survey]
    WHERE [QUESTION6] = '1 Time' AND MONTH([TICKET_CLOSED]) = @MONTH AND [SUPPORT_GROUP] IN (@SUPPORT_GROUP)
    GROUP BY Month([TICKET_CLOSED])
        ,YEAR([TICKET_CLOSED])
        ,DATENAME(MONTH, [TICKET_CLOSED])
    ) AS T1
    ,(
        SELECT cast(count(*) AS DECIMAL(5, 2)) AS CASESCOUNT
            ,DATENAME(MONTH, [TICKET_CLOSED]) AS [MONTH NAME]

你的第一个SELECT有2列，[FCRR]和类别。您尝试SELECT的另外两个UNION ALL必须有这两列（或至少相同的数据类型）。两者都缺少与Category列对应的那个。

您可以通过添加默认的硬编码值（SELECT cast(100 * ([FCRR] / CASESCOUNT) AS DECIMAL(5, 2)) AS [FCRR], 0 as Category）或实际从数据表中选择它们来解决它（如果它对应）。

调试的第一条规则：简化问题。

  • 你有3个部分UNIONed在一起;首先尝试其中两个的组合，以重新计算您需要查看的金额。
  • 分别运行每个查询并查看它返回的列数。这是错误消息的意思是“目标列表中的表达式数量”。
  • 从简单的查询构建，了解每次添加的内容。
